ELECTRlCALLY-OPERATED BRUSH.

SPECIFICATION fOIming part of Letters Patent No. 600,383, dated. March 8, 1898.

Application filed March 1, 1897. Serial No. 625,494. (No model.)

To all whom it may concern:

' Be it known that I, ALFRED SHERWOOD, of Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Electrically-Operated Brush,of which the following is a full, clear, and exact description.

My invention is an improvement in the class of hollow cylindrical rotary brushes which are provided interiorly with an electric motor and are particularly adapted for the use of barbers.

The features of novelty are the construction, arrangement, and combination of parts, including the brush proper and the motor and their bearings, and the yoke or bifurcated hanger by which the other parts are suspended.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my device. Figs. 2 and 3 are end elevations thereof. Fig.

4 is a longitudinal sectional view, and Fig. 5

is a cross-sectional view taken upon the line 5 5 of Fig. 4,

The object of my invention is to construct a brush, more particularly for barbers use, which may be connected with power for operating it and be of a compact form readily managed. The brush itself is constructed as a hollow cylinder B, the backing for the bristles being shown at B. This cylinder is open at each end and is provided with heads 13 and E the latter being perforated to enable the interior to be inspected without taking the heads off.

The yoke A for supporting the brush is provided with two arms A and A the former being removable from the body of the yoke and attached thereto by a screw to. The yoke A has attached to its outer end a tube D, which has at b a bearing for the head 13 of the brush-cylinder to turn upon. This tube extends within the brush-cylinder and is provided with a yoke or bar D upon its inner end which supports one end of the frame E of the motor. The opposite ends of the bars E, forming the frame of the motor, are attached to a yoke or bifurcated hanger F.

The motor M used in my device is an ordinary electric motor and has nothing novel in its construction. Its construction is therefore not illustrated or described in detaih One end m of the shaft of this motor is journaled in the inner end of the tube D. The other end m of the motor-shaft passes through the journal of the opposite end of the brushcylinder and into the arm A of the frame, in which it turns. This outer end of the motorshaft is provided with a pinion P, which meshes with a gear P, mounted upon a stud 19. To the gear P is attached a pinion P which in turn meshes with a gear P attached to the head B of the brush-cylinder. The speed of the motor is thus reduced before the power is applied to the brush-cylinder.

It will be seen that the field-magnets of the motor are rigidly attached to the parallel bars E, constituting part of the motor-frame, and are thus held stationary or rigid with the yoke or hanger A. The detachable arm A of the hanger is bored transversely to receive and furnish a bearing for the motor-shaft m, and its lower end is enlarged and provided with a vertical slot 0 to receive the shaft-pinion which meshes with the large gear P of the train.

The wires J, leading the current to the motor, are introduced through the tube D, as clearly shown in Fig. 4;. The commutator of the motor is shown at G. The wires J are carried to a switch 0, placed upon the upper side of the frame. This switch may be turned by means of the key or handle 0, so as to throw the current upon the motor or to switch the same off. The frame A is provided with an eye a, passing through ahole in its upper end and to which a cord for suspending the frame and brush may be attached. This cord may be supported in any desired wayas, for

instance, by passing over a pulley and having the motor and rotating on the aforementioned frame portion D, and provided with the hub gear P and the gear I and pinion P carried by hanger-arm A and meshing respec- I5 tively with the aforementioned motor pinion and hnbgear, as shown and described.
